Why am I getting this error if the web form otherwise works properly?
I inserted an Xml control into a web form. The Xml document source is an XML file, with the structure below. The transform source is the XSLT file below. The XSLT file should use the data in the XML file to create a list of hyperlinks. This works when
I test it - the hyperlink shows up and has the correct URL when I hover over it. The rest of the web form also loads properly. But, I get this error:
This is apparently a known bug in VS 2013. I inserted the following into the web.config file and the error no longer occurs. I'm not sure what problem this fixes or how it fixes it, but so far it has worked.

XML control has runtime error: syntax error, unrecognized expression

JavaScript runtime error: Syntax error, unrecognized expression: ?xml
I created an Xml control in the page source:
<asp:Xml ID="periodicalList" runat="server" DocumentSource="~/App_Data/periodicals.xml" TransformSource="~/stylesheet/periodicalDDL.xslt"></asp:Xml>
The xml file:
<periodicals>
<periodical name="test" pre="0" type="journal" id="000001" />
</periodicals>
The xslt file:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<div>
<xsl:for-each select="periodicals/periodical">
<xsl:element name="a">
<xsl:attribute name="href">
<xsl:text>/db/</xsl:text>
<xsl:value-of select="@type" disable-output-escaping="yes"/>
<xsl:text>.aspx?id=</xsl:text>
<xsl:value-of select="@id" disable-output-escaping="yes"/>
</xsl:attribute>
<xsl:attribute name="target">
<xsl:text>_blank</xsl:text>
</xsl:attribute>
<xsl:value-of select="@name" disable-output-escaping="yes"/>
</xsl:element>
<br />
</xsl:for-each>
</div>
</xsl:template>
</xsl:stylesheet>

I tried adding the Xml control in the .cs code-behind, rather than in the .aspx. Same problem.
if (Page.IsPostBack == false)
{ Xml loadPubs = new Xml();
loadPubs.DocumentSource = Server.MapPath("~/App_Data/periodicals.xml");
loadPubs.TransformSource = Server.MapPath("~/stylesheet/periodicalDDL.xslt");
right.Controls.Add(loadPubs);
}

This is apparently a known bug in VS 2013. I inserted the following into the web.config file and the error no longer occurs. I'm not sure what problem this fixes or how it fixes it, but so far it has worked.
<appSettings><add key="vs:EnableBrowserLink" value="false" />
</appSettings>
